Exactly, I don't see it possible in this situation. Generally it is something agreed upon and here I don't see the possibility, especially because of the amount of time that Sophie has been lying to him for cheating, it shouldn't be a situation that Felix endures more than anything because when the time comes, Sophie will be closer to Zack than to him, talking about lovers. I think the relationship between Sophie and Felix, I already see it on her part as something more like the love of friends.
